HTV silicone rubber ELASTOSIL® R plus 4070/20 is a self-bonding, addition-curing, one-component compound for the manufacture of press-cured articles Properties: The primerless, self-adhesive grade adheres to various plastic substrates (e.g. PA, PBT) and metals without tack formation to the mold. The bonding properties can be improved by a post-curing process (e.g. one hour at 100 °C) or by a longer storage at room temperature. Because of the individual surface properties each substrate must be tested before serial production. The vulcanizates are transparent and noted for good mechanical and electrical properties.
